SKSpriteNode 替换为 SKTexture

Question

我的问题是，当我玩我的游戏时，即使敌人没有碰到我的角色，但离他很近，我也会失去生命。我明白问题是我角色的透明space和敌人的透明space.

有接触

我想按照SKPhysicsBody documentation中的建议去做。我如何使用我当前的代码实现它？

func madEnemy() {

    let randomNumber = Int.random(in: 1..<6)

    let enemy = SKSpriteNode(imageNamed: "enemy\(randomNumber)")

    enemy.position = CGPoint(
        x: cameraRect.maxX + enemy.size.width/2,
        y: CGFloat.random(
            min: cameraRect.minY + enemy.size.height/2,
            max: cameraRect.maxY - enemy.size.height/2))
    enemy.zPosition = 50
    enemy.name = "enemy"
    addChild(enemy)

    let actionMove =
        SKAction.moveBy(x: -(size.width + enemy.size.width), y: 0, duration: 2.0)
    let actionRemove = SKAction.removeFromParent()
    enemy.run(SKAction.sequence([actionMove, actionRemove]))
}

您只需要先从您的图像创建一个 SKTexture 对象，然后使用该纹理创建一个 SKSpriteNode 以便使用该纹理调整 SKPhysicsBody 或您的节点的大小.

func madEnemy() {

    let randomNumber = Int.random(in: 1..<6)

    let enemyTexture = SKTexture(imageNamed: "enemy\(randomNumber)")
    let enemy = SKSpriteNode(texture: enemyTexture)
    enemy.physicsBody = SKPhysicsBody(texture: enemyTexture, size: CGSize(width: enemy.size.width, height: enemy.size.height))

    enemy.position = CGPoint(
        x: cameraRect.maxX + enemy.size.width/2,
        y: CGFloat.random(
            min: cameraRect.minY + enemy.size.height/2,
            max: cameraRect.maxY - enemy.size.height/2))
    enemy.zPosition = 50
    enemy.name = "enemy"
    addChild(enemy)

    let actionMove =
        SKAction.moveBy(x: -(size.width + enemy.size.width), y: 0, duration: 2.0)
    let actionRemove = SKAction.removeFromParent()
    enemy.run(SKAction.sequence([actionMove, actionRemove]))
}
